IMPROVEMENT IN W ATE R-M OTORS.

Specification forming part of Letters Patent No. 201,511, dated March19, 1878; application filed a February 9, 1878. y

v State of Pennsylvania, have invented a new and Improved Water-Motor,and I do hereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the accompanyingdrawing, forming part of this specification, in which- Figure l is aside view of the device with one-half of the case removed. Fig. 2 is avertical transverse section through the case. Fig. 3 is a plan view ofthe lower half of the case with the wheel in section. Fig. 4. is adetail sectional view of one of the nozzles,

showing the diff'erentsized channels in the" plug-valve or stop-cock.

My invention relates to certain improvements upon that form ofwater-motor designed to be operated by the pressure of water from thestreet-mains, a tank upon the top of the house, or other suitable head,for the purpose of driving light-running machinery, suchvassewing-machines, scroll-saws, &c.

The particular class of motors to which my employs a wheel havingbuckets upon its periphery, against which the stream of water is made toimpinge to rotate the shaft upon which said wheel is placed.

My improvements consist in the peculiar construction of the wheel madeof two convex disks,with a trough-shaped periphery, carrying two rows ofbuckets; in the construction of the case, which is divided horizontally,and arranged for easy separability of parts; and in the peculiar devicesfor preventing leakage at the joints, as hereinafter more fullydescribed.

In the drawing, A A represent the outer case, containing the wheel,which case is divided horizontally through its center, and of which thelower half .is provided with a flanged support, (1., having screw-holesfor securing the same. Upon the upper surface of the said lower half ofthe case are formed bearings b b, in which is journaled the shaftB,carrying the waterwheel. Said bearings are placed a littleeccentrically to the case, so as to give room upon one side for thenozzles.

O is the wheel, which is rigidly fastened to the shaft. Said wheel isconstructed of two convex disks, placed together, so as to be thick nearthe center and thin near the periphery, around which is secured atrough-like rim,

D, having a partition, 0, and upon each side and that the body of thesamehas been stamped outof sheet metal, and finished with radial spokesand a trough-shaped rim; but my con-j struction'of wheel, it willbe'seen, has a long bearing upon its shaft, and hence is more stifflyconnected thereto. Being made of sheet metal, it possesses the requisitelightness; and its sides being continuous surfaces instead of separateradial spokes, it moves freely without spatterin g and withoutretardation if the water should chance to rise above the troughshapedrim.

This wheel, which is designed to be run solely by the percussive forceof the water, and not by the weight of the same, receives its water froma supply-pipe, E, passing through the lower half of the case, anddischarges its water into the bottom part of the case, whence it runsout through the exit-pipe 0. After the supplypipe passes into the case'it then branches into two nozzles, f f, one of which is in position toplay upon one of the rows of buckets, and the other upon the other row.Each of these nozzles is provided with an independent plug-valve orcock, g g, each of which has several ways or discharge openings (seeFig. 4.) in the same of different sizes, and which plugs extend throughthe side of the case to a position within convenient reach for operatingthe same. By turning these plugs a distance indicated by an index-handand dial on the outside, the different sizes of discharge-apertures arebrought into registration with the supply-pipe, and a solid andeffective stream of varying sizes may thus be obtained, either of whichmay be used, according to the work required.

In constructing the upper half of the case, it is made of two pieces ofsheet metal, h h, struck up, united by screws or rivets, and galvanized.The said upper portion of the case is slotted to fit down over the endsof the shaft, and its lower edges all around are flanged inwardly, topass into and fit nicely with the outwardlyrflared upper edge i of thelower case. To make this jointtight, a lining, j, of rubber is placedinside the flared lips of the lower half of the case, which causes theinner flange of the top part of the case to bind therewith and preventleakage, and at the same time affords means for holding the top half ofthe case without other fastening device, and in such a manner as topermit it to be readily removed for inspection or repairs.

To prevent leakage through the bearings of the shaft, disks k k arerigidly fixed thereon between the wheel and said bearings; and toprevent the drippings from the upper half of the case from leaking outat the slots cut in the upper half of thecase for the reception of theshaft, undercut strips or ledges l are arranged upon this part of thecase upon each side above these points, which compel the water to dropdown into the lower portion of the case.

Having thus described my invention, what I claim as new is' 1. The wheelconstructed of plain convex sheet-metal disks, provided with atroughshaped peripheral rim containing buckets,

I substantially as described.

2. The case divided horizontally, and having the lower half flaredoutwardly at its upper edge, and the upper half flan ged or flaredinwardly at its lower edge, combined with each other for easyremovability, substantially as described.

3. The lower half of the case having its upper edge flared outwardly,and provided with a lining of rubber, combined with the upper halfhaving an inward flange, to form a tight joint, substantially asdescribed.

4. The wheel-shaft provided with disks 70 k, interposed between thewheel and the bearings of the shaft, to exclude the water from thelatter, as described.

5. The upper halfof a horizontally-divided case, made slotted toaccommodate the shaft, and provided with undercut strips 1 about suchslots and its lower edges, to keep the water from passing out at thesepoints, as described.
